在初中数学中,勾股定理是几何学习过程中非常重要的一个定理,它不仅具有深刻的历史底蕴,而且与直角三角形有关问题有着密切的联系.所以,在讲授该定理时,教师有必要严谨地设计方案,让理论依据和教学思路都能清晰地呈现在课堂当中.只有这样,学生才可以更好地学好知识,领悟勾股定理,实现学习目的.本文以勾股定理的实际教学作为案例,将方案设计规划为如下五步. In junior middle school mathematics, the Pythagorean theorem is a very important theorem in the process of geometry learning, which not only has a profound historical background but also is closely related to the problems related to right-angled triangles.Therefore, when teaching this theorem, teachers need to be rigorous So that the theoretical basis and teaching ideas can be clearly presented in the classroom.Only in this way, students can better learn knowledge, comprehend the Pythagorean theorem, to achieve the purpose of learning.In this paper, the teaching of the Pythagorean theorem as a case , The program design for the following five steps.
